srncrrrcarron forming .Zfo all who??? it may concern:

Be it known that I, \VILLIAM Gunner lHEN DERsoN, of Sulphur Springs, in the county of Hopkins and State of Texas, have invented a new and useful Improvement in SulkyPlows, of which the following is a full, clear, and exact description.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure l is a side elevation of my improvement. Fig. 2- is aplan view of the same, partly in section. Fig. 3 is a front elevation of a part of the same, partly in section. Fig. 4 is a sectional plan view of a part of the same, taken through the line as m, Fig. 3.

The object of this invention is to promote. convenience in operating sulky-plows.

The invention consists in asulky-plow constructed with the sliding. block carrying the adjustable wheel locked in place by a sliding spring-pressed bolt and withdrawn by means of an elbow-lever. The sliding wheel-carrying block is provided with rack-teeth engaging with the teeth of a double-gear wheel. placed loosely upon the journal of the plowcran'k, and connected with the ploworank le-.

ver by a pawl, whereby the machine can be leveled and the plow adj nsted by means of the same lever, as will be hereinafter fully described.

. A represents the frame of the machine, to. the upper part of which is secured the tongue 13. The connection between the tongue Band the frame A is strengthened by the brace (I, the upper end of which is secured to the said tongue, and its lower end is secured to the lower part of the upright side of the said frame.

To the top of the frame A is secured the lower end of the spring-standard D, to the upper end of which is secured the driver sseat E.

To the rear lower parts of the upright sides of the frame A are journaled the ends of the crank F, to which is secured, by clamps G or other suitable means,the beams H of the plow I.

J is one of the sulky-wheels, the journal K of which is stationary, and is attached to one of the upright sides oftlie frame A. The other wheel, L, revolves upon the journal M, at

part of Letters Patent No. 286,433, dated October 9, 1833.

Application filed June 29, 1883. (N0 model.)

tached or formed upon the dovetailed block N, which slidesin a dovetailed groove in the outer side of the lower part of the upright side of theframe A. N are formed recesses O,to receive theend of the bolt 1, which slides in a bearing in ,the upright side of the frame A and in abracket, Q, attached to the inner side of the said part of the frame engage with the sliding block N by a spiral spring, It, placed upon the inner part of the said bolt, with one end resting against the brackets Q and its other end resting against a shoulder formed upon the said bolt P, as shown in Figs. 3 and 4.

In the inner part of the bolt P is formed an opening to receive the end of an elbow-lever, S, which is pivoted at its angle to a support attached to the frame A. The other arm of the lever S projects into such a position that it can be readily reached and operated by the driver with his feet to draw the bolt 1? inward and release the block N. Upon the rear edge of the outer part of the block N are formed rack'teeth T, with which engage the teeth of the inner part of the doublegear wheel U. The double-gear wheel U revolves loosely upon the journal of the plowcrank F,between the frame A and the lever V, rigidly attached to the end of the said plowcrank journal.

I Viththe teeth of the outer part of the double gear wheel U engages the pawl XV, which worksin keepers attached to the lever V, and is held down by a spiral spring, X, placed upon it. To the upper end of the pawl \V is attached the lower end of the rod Y, the upper end of which is attached to the small elbow- In the inner side of the block A. The bolt 1? is held outward to lever Z,pivoted to the upper part of the lei/ eg/ be desired, so that the machine can be leveled and the plow adjusted by means of a single lever. I

I do not abandon or dedicate to the public any patentable features set forth herein and not hereinafter claimed, but reserve the right to claim the same either in a reissue of any patent that may be granted upon this application or in other applications for Letters Patent that I may make.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1 1. A sulky-plow constructed, substantially as herein shown and described, with the sliding block carrying the adjustable wheel locked in place by a sliding bolt and operated by a loose gear-wheel connected by a pawl with the adjusting-lever attached to the plow-crank, as set forth.

2. In a sulky-plow, the combination, with the frame A and the sliding block N, carrying the Wheel L, of the sliding bolt P, the spring R, and the elbow-lever S, substantially as herein shown and described, whereby the said block can be readily released, as set forth.

3. In a sulky-plow, the combination, with the sliding block N, carrying the wheel L and provided with rack-teeth T, the plow-crank F, and the rigid lever V, provided with the pawl WV, of the double-gear wheel U, substantially as herein shown and described, wherel by the machine can be leveled and the plow adjusted by means of the same lever, as set forth.
